How is the CAS seeing the replication links for this primary and its sites? Are the database and SQL services up and running on all the servers (DB, port configuration, TCP/IP, etc)? Any firewalls in between? Were they working before? If so, what change was implemented? Did you check spdiagdrs for any indications? Did you run RLA and examined the results?Tuesday, December 27, 2016 3:33 PM

Normally, even if the CAS can't replicate Primary, you should still have a link to the secondary boxes. I think this indicates a broader issue like a port or a recent change to all the machines like a sql update or services are stopped.

When you use the Replication Link analyzer tool, what does it say as the error?
Do you have any errors in your SQL logs on the CAS?

are you still on 2012 or have you moved to 1511? are you running custom ports for SQL or a custom Named instance for your database? There is a hotfix necessary to install after the upgrade to make Replication work again, this isn't necessary if you move to 1602 or higher.
